Not really exciting, this season opening. It felt like the writers wanted to introduce Dexter again, but they didn't add anything new. Same story with Rita, she is sweet and Dexter's relationship with the kids is cute to watch. But still, we know that already. Same story with Deb, she will probably fall for the wrong guy AGAIN (Quinn).
Same story with Dexter, yes he follows the code, but accidents happen. He luckely finds a way to erase the evidence. Maybe the new character Prado will be interesting. He's already on to something with Dexter. That was a good twist where he asked why he was investigating his brother. And the last thing we need is a little Dexter running around! So it was good, but not great. Still, I'll give it a change, just because the previous seasons were so good.
